Canadian tire has them if this is what your talking about. No doubt you'll have to add some additional filtration, and even during the summer, keeping the pool heated at night is going to be a concern if last year was any indication.
Good luck.
Edit: I should also add that I know for a fact you can get like a netting that just fits over top of these... keeps the leaves and stuff out as well as stops the fish from jumping out. Shouldn't hurt the fish imo
